STATES DISPENSING CONTAINER 1 COLLAPSIBLE LINER Application August 14, 945, Serial No. $193M 1 Claims. (Cl. 222-95) This invention relates to a dispensing device and more particularly to a can in which oils and grease may be shipped and from which said substances may be readily removed.

The primary object oi the invention is to insure cleanliness in handling oils and grease such as lubricants employed in the lubrication oi motor vehicles, and the like.

Another object is to facilitate the loading of grease guns and similar pieces of equipment with the contents of the can.

A further object of the invention is to avoid leakage of the cans contents during the filling of a grease gun or like piece of equipment.

The above and other objects may be attained by employing this invention which embodies among its features a shipping container in the form of a cylindrical body which is wholly open at its top and adapted to be closed by a removable cover, a collapsible liner fitted in the tubular body and in a closed bag of flexible material having a dispensing outlet in its top which aligns with the longitudinal axis of the outer container, a dispensing nipple surrounding the outlet, and a follower of a size readily to telescope within the outer container but covering the entire outer end of the liner surrounding the nipple whereby pressure applied to the follower will cause the contents of the liner to be extruded through the nipple for discharge either into a discharge spout or directly into the barrel of a grease gun or similar piece of equipment.

In the drawings:

Figure 1 is a perspective view of a dispensing device embodying the features of this invention showing the cover removed from the shipping container,

Figure 2 is a longitudinal sectional view through the device illustrated in Figure 1,

Figure 3 is an enlarged detail fragmentary sectional view through the upper end of the device, and

Figure 4 is a side view of the dispensing device showing the dispensing nozzle in position thereon.

Referring to the drawings in detail, a shipping container ll comprises a cylindrical body II which is open at its upper end and adapted to be closed for shipment by a cover (not shown). The body H is of the usual size and shape to accommodate the type of lubricant ordinarily shipped therein and is provided with a fixed bottom I! so that when the cover is in place the device forms a completely closed chamber.

2 Fitted in the body is a collapsible liner is which is in the form of a flexible bag, the upper end of which is closed by an end wall it having a cen tral opening it into which a dispensing nipple I6 is fastened in any suitable manner, as by wind ing string or the like about the junction of the top it and the nipple it. It is obvious that any suitable type of seal may be employed between the bag top It and the'nipple which will prevent the escape of the contents of the liner is around the outside of the nipple.

Secured to the nipple it as by a threaded connection is a follower H which takes the form of a metal disk of a diameter to telescope within the body it. This follower is provided with an annular upturned flange it at its periphery which is positioned close to the side walls of the container ii and radial reinforcing depressions I! are preferably formed in the follower to insure that it will remain at all times flat. Seated on the upper side of the follower and surrounding the nipple i6 is a washer it of felt or similar soft, pliable material which will serve as a seal when the open end of a grease gun is placed over the nipple It. This washer 20 also serves as a seal when the spout, to be more fully hereinafter described, is placed in position on the dispensin device.

The spout above referred to is designated generally 2| and comprises a straight nipple 22 which terminates at one end in an enlarged socket for threaded connection with the exterior of the nipple l6. Attached in any suitable manner to spout member 23 which is of a length the opposite end of the nipple 22 is a U-shaped to extend slightly beyond the radial distance between the nipple i6 and the side of the body H. The function of this spout 2i and the parts forming it is obvious from an exa ation of Figure 4, and when the device is being shipped the parts 22 and 23 may be separated and placed in position on the top of the follower it, as suggested by the dotted lines in Figure 1. It will thus be seen that the spout as a whole may be accommodated in the space between the cover of the container i0 and the upper side of the follower during shipment. 1

The operation of the device is more or less obvious, as it is apparent that the open end of a barrel of a grease gun, after the cap has been removed therefrom, may be placed over the nozzle l6 and against the washer or gasket 20 so that when downward pressure is exerted on the follower the contents of the liner i3 will be extruded through the nipple it and into the barrel of the gun or other piece of equipment to be loaded. Due to the fact that the gasket 20 is of relatively soft, pliable material, it is obvious that no leakage between the end of the gun barrel and the follower or nipple it the contents of the liner I! be of such a light viscosity as to render it impractical to 1111 a gun barrel as above suggested, the nozzle 2| may be placed in position, as illustrated in Figure 4, and when downward pressure lower II, the contents of the collapsible liner l3 will be forced upwardly through the spout and then directed downwardly into the barrel of the gun or other piece of equipment to be loaded.

Should 5 is applied to the fol- While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having thus described the invention, claim is:

hollow collapsible liner within the body, a dis charge nipple on the end of the liner adjacent the open end of the body, a follower surrounding the discharge nipple and covering the end of the liner through which the discharge nipple extends whereby the contents of'the liner may be extruded through the nipple when pressure is applied to the follower, and cover on the container forming in conjunction with the follower a chamber in I and covering the end of the liner entered by said nipple whereby the contents of the liner may be extruded through the nipple when pressure is applied to the follower, a sealing gasket surmounting the follower and surrounding the nipple, a discharge spout adapted. to be connected to the discharge nipple and seatedagainst said gasket and a cover for the body forming in conjunction with the follower a chamber'in which the discharge spout may be housed during shipment of the container.

5. A shipping and dispensing device of relatively large capacity comprising a hollow cylindrical body wholly open at one end, a cover to close the open end of the body during shipment, a hollow'collapsible liner within the body forming with the cover a chamber at the top of the body, a discharge nipple entering the end of adjacent the chamber, said discharge nipple extending into the chamber, a follower surrounding the discharge nipple and covering the end of the liner through which the discharge nipple enters the chamber, whereby the contents of the liner may be extruded through the nipple when pressure is applied to the follower, and a dispensing nozzle adapted to be coupled to the nipple.
